摘　　要：X9桥是一座三跨预应力混凝土部分斜拉桥。以该桥为工程背景,分析了主梁刚度、主塔刚度和拉索截面积等参数变化对结构静力性能和动力特性的影响。分析的结论对此类桥梁的设计提供了借鉴。X9 Bridge is a three-span partly cable-stayed PC bridge, based on which, analysis is made of the impact on the static performance and dynamic behavior of the structure caused by variation in coefficients such as the rigidity of the main girder and the main pylon and the cross section area of the cable. Conclusion from the analysis is a good reference for design of similar bridges.
